摘要

A new Australian eriococcid genus Fragorbis gen. nov. (Hemiptera: Coccoidea) is described for Sphaerococcus pustulans and four new species, F. fructus sp. nov., F. pseudopustulans sp. nov., F. stipites sp. nov. and F. superfacies sp. nov. Four of the five species are known only from Victoria and the fifth species from the High Country east of Tumut in New South Wales. All species feed on Eucalyptus, either in blister galls, or under or on the bark. The adult female of each species and the first-instar nymph of F. pseudopustulans are described and illustrated. Keys are provided to the adult females of the eriococcid genera found on Eucalyptus and Corymbia, and to the species of Fragorbis..
